"Responding to consumer comments on the new device, and to coverage from other reviewers, we also carried out further tests that confirmed the new iPad is warmer in its hottest spots than the iPad 2," the magazine said this morning. "But we didn't find those temperatures to be cause for concern."

Using a thermal imaging camera, Consumer Reports recorded the high temperatures on both the front and rear of the new iPad while playing Infinity Blade II. CR said the temperatures were much warmer than the iPad 2.

Apple officials maintain that the new iPad operates within acceptable limits.
